Perhaps, but maybe not...I guess it depends on what types of "crashes" you 
experience.  In my case, a crash usually means "continuous reboot", so I'd much 
rather have on_crash set to "destroy" than "reboot" as I'd rather not have Xen 
sit there and constantly reboot a machine that crashes - usually a Windows 
machine that's done an update and is BSODing, rebooting, BSODing, etc.
